The color ink cartridge is expended even though I print in black only. Why does this happen?
To keep the print head clear and ready to print, the printer uses a small amount of ink from all the cartridges whenever it prints. Even if you select Black/Grayscale (Windows) or Grayscale (Mac OS X), some color ink is still being used.
